UNITED STATES PATENT. OFFICE AUGUSTUS J. FRAME, OF COLUMBUS, OHIO, ASSIGNOR TO FRANKLIN OIL HEATING, INC.,

OF COLUMBUS, OHIO, A CORPORATION OF O HIO .OIL BURNER CONSTRUCTION Application filed January 22, 1930. Serial No. 422,510.

This invention relates to oil burner construction and has for its object to provide a new and improved means of mounting an oil burner or fuel burning apparatus.

Hitherto, particularly with respect to oil burners of the vaporizing type utilizing a retort or pot for the maintenance of a pool of oil which is gasified for combustion, it has been customary to install the pot or retort as nearly level as possible in the firebox of the heating apparatus, after which the duct by which air is conveyed to the retort and firebox is sealed in the door or aperture through which it enters the firebox. A fairly accurate leveling of the pot or retort is necessary for proper operation, and frequently only a test under actual operating conditions will determine whether or not the proper leveling has been obtained. If, as frequently happens, the pot has not been set with suflicient accuracy and with proper leveling, it is necessary to tear down the means sealing the entrance for the air duct and endeavor to relevel the pot inside the furnace. These operations may have to be repeated several times and add much to the difliculty and expense of installation.

With my invention, disclosed herein, it is possible to quickly and readily mount the pot in the firebox and thereafter to level it, even during operation, from outside the furnace.

These and other objects and the structure whereby they are accomplished will be more fully described and set forth in the following specification, and as shown in the accompanying drawings in which:

Fig. l is a plan view of my invention showing in more or less diagrammatic form in cross section the firebox;

Fig. 2 is a side elevation of the structure illustrated in Fig. 1;

Fig. 3 is a vertical section along the line 3-3 of Fig. 2, being drawn to enlarged scale;

Fig. 4 is a front elevation of the closure means; i

Fig. 5 is a horizontal section 55 of Fig. 4; and

Fig. 6 is a vertical section along the line 66 of Fig. 3.

Like numerals refer to like elements along the line throughout the drawings in which 10 indicates generally the wall of a furnace or other heating apparatus which encloses the firebox and ashpit lO-a. The front wall is provided witzl: the usual ash door opening or the like 10- 12 indicates generally a pot or retort par ticularly designed for the burning of oil, it. being unnecessary to describe this portion of my invention in particular detail other than to mention that it includes an external casing 12-a, an inner retort to which oil or fuel is supplied and a central air distributing pipe 12-12. In the bottom of the casing is mounted a bridge or reinforcing member 14, shown as attached to the casing b means 'of rivets 15 or the like. This mem er is provided with upstanding flanges 14-a at its extremities which are similarly secured to the Wall of the casing. At its central portion the 7 member 14 is upwardly bent and recessed as indicated at 14-6 to provide a recess 14-0. Adjacent this recess the bottom of the casing 12-a is apertured and the portion surrounding the aperture is inturned to lie against the 7 surface of the recess 14-0.

A supporting member 16 is provided, being of elongated contour and provided with one supporting leg 16-a at one end and a pair of spaced supporting legs at the opposite end. Above the legs flanges 16-d project upwardly at each end for purposes hereinafter described. From the central portion of the member 16 upwardly projects a boss 16-0 rounded at the top and of such dimension as to easily fit in the recess 14-0. This provides a species of swiveling mount for the pot or casing, as is illustrated in Fig. 3 for example, the flanges 16-d being located outwardly of the casing 12-a and above the base thereof, the arrangement bein such that the pot 12-a may be freely rotate or sw'iveled upon the boss 16-0 Without interference from the flanges 16-03, at least within that range of movement which is desirable or necessary for adjustment of position 'of the pot. The flanges 16-e prevent lateral displacement or shift of the pot upon the supporting member 16.

In the embodiment of my invention illns- 9 7 is rigidly secured to the casing 12-a at one end. At its other end the duct 20 is coupled or attached to the outlet end 21-a of a fan ,casing 21 so that it may be rigidly secured thereto. A fan of any suitable construction (not shown) is located in the casing 21 and is driven by the motor 22 mounted upon the table 23 upon which is also mounted (in the form shown) controlling mechanism located with box or casing 24. It is not necessary to illustrate or describe this control mechanism herein. The fan casing 21 is provided with air inlets 21-?) controlled by rotatable damper or valve 26. It will be apparent that the control mechanism, motor, fan and, to a certain extent, the duct 20 are supported by the table 23.

At three corners of this table 23' are provided supporting legs 28 slidably mounted in suitable apertures and secured in adjusted position by means of set screws 29.

Surrounding the duct 20 is what I have termed a closure member or means generally indicated by the numeral 30 and comprising a relatively fixed plate 30-a having a rear- Wardly extending tubular portion 30-?) and being overturned at its sides as indicated by numeral 30-0. Slidably mounted, in the channels provided by these overturned sides 30-0, is the relatively movable plate 30-05 apertured to closely fit around the duct 20, being flanged at 30-6 to provide a snugger fit for the duct while permitting relative rotation of the duct with respect to the plate.

After placement of the pot or retort in the chamber, firebrick or refractory material, generally indicated by numeral 35, is utilized to fill'or seal the opening 10-6, being arranged to closely fit and engage the tubular portion 30-6 as illustrated in Figs. 1 and 2, for example. The fixed and movable plates comprising the closure member 30 are. located at the outside of the wall formed by the refractory material 35.

In the use of my inventiorr in installing the mechanism, the supporting member 16 is first positioned in the desired location in the firebox, being supported directly upon the floor of the firebox or upon firebri'ck, or the like, as may be necessary to bring the pot to the desired height. This supporting member 16 may be easily located so as to be approximately level, but some irregularity in the floor of the firebox may preclude its being mounted exactly level, as is frequently the ease. The casing 12-0 is then mounted upon the box 16-6 and the duct 20 coupled to the fan casing 21-a, after which the aperture or door-opening 10-6 is closed up, as illustrated in Figs. 1 and 2. The legs 28 being adjusted to obtain as nearly'a level condition of the pot as is possible to obtain byestimate, the apparatus may be set in operation. Observation of such operation will enable the skilled workman to determine whether or not the pot is properly leveled, so that the depth of oil maintainedin the pot is substantially uniform over the bottom thereof. If it appears from observation that the pot is not properly leveled, it is not necessary to tear down the sealing refractory 35 and endeavor to level the pot inside of the firebox, a difficult job at best,

burning mechanism of the character illustrated may be readily and quickly installed and may be accurately and truly leveled from without the furnace or heating apparatus to obtain proper combustion.

While I have illustrated and referred to the oil receiving and burning element 12 as a pot, it will be apparent that other shapes of fuel receiving devices may be substituted Without departing from the spirit of my invention, and in general I do not wish to be restricted to the embodiment illustrated and described in the drawings and specification, respectively, except as I may necessarily be restricted thereto by the appended claims properly interpreted in View of the prior art.
